- DHW heating is not blocked by the time program
There is a current demand for domestic hot water when the water
temperature in the DHW cylinder is 5K lower than the selected
set DHW value.
4.3.1 DHW mode selection
The appliance features two different operating modes for DHW
heating:
- Automatic mode
- Quick heat-up
In automatic mode, DHW heating is controlled via an individually
adjustable time program. The DHW is heated using all the heat
sources which are enabled for automatic mode (see chapter "Pa-
rameter level/ Parameter setting").
In quick heat-up mode, the water is heated immediately to the
selected set DHW value, irrespective of automatic mode. Once the
selected set DHW value has been reached, the appliance switches
back to automatic mode.
Note
Automatic mode is the default factory setting.
